If you listen to the last bit of this video of a cheetah purring it is quite impressive. The recording is good which helps but the purr is very strong. Below the video is another showing the waveform of the sound.

The order of breathing in the video immediately above is: egressive (out) — ingressive (in) — out –- in -– out -– in

There is a bit of background noise in the video below of Rocky a domestic cat but the differences in the purr are apparent:

We all know that cats purr continuously which means they purr when breathing in and out and even when drinking (kitten suckling). The differences in sound between the egressive (out-breathing) and ingressive (in-breathing) phases of the cheetah’s purr are clear but less clear for the domestic cat.

The cheetah is Caine and the recording was made in South Africa. The roaring big cats cannot purr. All the other wild cat species can. The wild cats tend to have a wider repertoire of vocalisations than the domestic cat. That is the impression I get from my reading. The leopard makes a sound that is very much like someone sawing wood. It is continuous and similar to a purr. You can hear the sound in an audio file here. I hope it works for you.

Another species of animal can purr and the sound is very similar to the domestic cat. This is the genet. The genet is the only animal other than the cat that purrs as far as we know. You can listen to the genet purr on this page. It is an audio file. It might not work and it opens in a new tab or window.

The purr is said to help heal an injured cat. It is a reason why cat’s purr. I wonder if because of that it also has a beneficial effect on people. I wonder if there is something about the purr that tweaks something in the brain that makes us feel better.

The first time i have heard a Cheetah purring. As for the cat’s purring, not much to differentiate from the Cheetah if a person is “Blindfolded” and listening.The Cheetah’s tone seems slightly higher in decibel level as it is a larger animal.

I was curious how cats purr. This is from Animal Planet.com:
“It turns out that cats have special wiring! The wiring travels from the brain to the muscles in the voice box, and this wiring is able to vibrate the muscles so that they act as a valve for air flowing past the voice box. The muscles work both during inhalation and exhalation, which creates the impression that cats can purr continuously. The air passes through the valve, which opens and closes rapidly to create the purring sound.”
